Cooling system for power storage

Abstract

An ECU performs processing including obtaining a full charge capacity when a cooling apparatus remains stopped, showing textual information that inquires about whether or not cooling can be carried out when a battery temperature is equal to or lower than a threshold value TB(1), when the full charge capacity is equal to or lower than a threshold value C(1), and when the battery temperature is equal to or higher than a threshold value TB(2), carrying out battery cooling control when a request for carrying out cooling has been issued, and maintaining a standstill state of the cooling apparatus when no request for carrying out cooling has been issued.

What is claimed is: 
     
       1. A cooling system for a power storage, the power storage being used for supply of electric power to a drive source of a vehicle, the cooling system comprising:
 a cooling apparatus that cools the power storage; 
 a notification apparatus that provides prescribed information in a compartment of the vehicle; and 
 an electronic control unit (ECU) programmed to: 
 control the cooling apparatus and the notification apparatus, 
 obtain a full charge capacity of the power storage, 
 wherein 
 based upon (i) an execution condition relating to cooling of the power storage being satisfied during stoppage of the cooling apparatus, and (ii) the full charge capacity being equal to or lower than a prescribed threshold value, provide inquiry information through the notification apparatus, the inquiry information representing whether cooling of the power storage with the cooling apparatus is carried out. 
 
     
     
       2. The cooling system according to  claim 1 , wherein
 the execution condition includes a condition that a temperature of the power storage is equal to or lower than a first temperature. 
 
     
     
       3. The cooling system according to  claim 1 , further comprising an operation apparatus that accepts an operation by a user, wherein
 when the operation apparatus accepts a cooling execution operation that requests for execution of cooling of the power storage in response to the inquiry information, the ECU carries out cooling of the power storage with the cooling apparatus. 
 
     
     
       4. The cooling system according to  claim 1 , further comprising an operation apparatus that accepts an operation by a user, wherein
 when the operation apparatus accepts a cooling non-execution operation that requests for non-execution of cooling of the power storage in response to the inquiry information, the ECU does not carry out cooling of the power storage with the cooling apparatus. 
 
     
     
       5. The cooling system according to  claim 3 , wherein
 when the operation apparatus accepts the cooling execution operation and then the execution condition is not satisfied and again satisfied, the cooling execution operation accepted by the operation apparatus is retrieved and the ECU carries out cooling of the power storage based on the cooling execution operation accepted again by the operation apparatus, and 
 when the operation apparatus accepts a cooling non-execution operation and then the execution condition is not satisfied and again satisfied, the cooling non-execution operation accepted by the operation apparatus is retrieved and the ECU does not carry out cooling of the power storage based on the cooling non-execution operation accepted again by the operation apparatus. 
 
     
     
       6. The cooling system according to  claim 3 , wherein
 when trip of the vehicle ends, the ECU resets information representing the operation previously accepted by the operation apparatus. 
 
     
     
       7. The cooling system according to  claim 5 , wherein
 when the operation apparatus accepts the cooling execution operation and then accepts an additional operation, based on the additional operation, the ECU carries out cooling of the power storage on condition that the execution condition is satisfied, and 
 when the operation apparatus accepts the cooling non-execution operation and then accepts an additional operation, based on the additional operation, the ECU does not carry out cooling of the power storage on condition that the execution condition is satisfied. 
 
     
     
       8. The cooling system according to  claim 1 , wherein
 when the power storage is in an abnormal condition, the ECU carries out cooling of the power storage with the cooling apparatus without providing the inquiry information, wherein the abnormal condition is at least one of: a battery temperature above a predetermined temperature threshold, a determination that the battery is in an overvoltage state, or a determination that the battery has a flow of an overcurrent. 
 
     
     
       9. The cooling system according to  claim 1 , wherein
 when a temperature of the power storage is equal to or lower than a first temperature and higher than a second temperature, the ECU provides the inquiry information, and 
 when the temperature of the power storage is higher than the first temperature, the ECU carries out cooling of the power storage with the cooling apparatus without providing the inquiry information. 
 
     
     
       10. The cooling system according to  claim 1 , wherein
 the ECU provides information that represents at least any of an advantage and a disadvantage in carrying out cooling, in addition to the inquiry information. 
 
     
     
       11. The cooling system according to  claim 1 , wherein
 the ECU provides information that represents at least any of an advantage and a disadvantage in not carrying out cooling, in addition to the inquiry information. 
 
     
     
       12. The cooling system according to  claim 8 , wherein
 when the ECU has carried out cooling of the power storage with the cooling apparatus without providing the inquiry information, the ECU provides, through the notification apparatus, information indicating that cooling of the power storage has been carried out. 
 
     
     
       13. The cooling system according to  claim 1 , wherein
 when the execution condition is satisfied during cooling by the cooling apparatus, the ECU provides, through the notification apparatus, information that inquires about whether a performance level of the cooling apparatus can be raised.
